EML to PDF: How to Merge .EML Files into One PDF Document?

PDF Logo

Eml files are individual email files that have been saved outside of an email client. Thunderbird is a popular client that saves emails as .eml files. For a variety of reasons, it is sometimes convenient to convert .eml files to different formats, such as PDF.

PDF is well suited for Email storage if you use the correct software.

When converting eml to pdf, consider how you want to structure your project. Questions you should answer before starting:

How many .Eml files are you working with?
If you have thousands of .eml files, then you will need software that can automate the export.

Do you need to convert .eml files to a single PDF or to individual PDF files?
Sometimes its more convenient to combine the .eml files into a single large PDF file.

How should file attachments be handled?
When converting email to PDF, file attachments are too often an afterthought, when they should be the main focus of the project. Consider whether the file attachments should be placed inside the PDF file as separate files that can be later extracted, or whether they should be combined into the PDF document image, or simply ignored.

Appending .EML Emails To An Existing .PDF File

Encryptomatic LLC, the developers of email viewing software, has released update 4.7 for both EML Viewer Pro and EML Viewer Lite.  These releases include PDF Append, a new pdf management feature for people who regularly need to save .eml files or other email file types to a single pdf file.

The PDF Append capability helps you convert an individual .eml file into a new or existing pdf file. This is a useful feature if you want to create a single pdf file that contains multiple email messages. One of the use-cases for PDF Append involved a legal assistant who was given the responsibility to collect specific email communications into a single pdf file.  Prior to this ability being added to EML Viewer Pro, she would export the messages individually and then use different software to merge the pdf documents into a single file, a process she found cumbersome and time consuming.

With PDF Append, she can now export these email messages to a new or existing pdf file. As the emails are discovered, she can append them to a single pdf document, with no need to run another software package.

To use this functionality, first start EML Viewer Pro or Lite and then select the folder containing your .eml files.  The software can also read .msg, .mht, .ost and Outlook .pst files.  Click on an email you want to export so it is highlighted in the mail list.  Now, click the +PDF button and enter a name for the file. The email message will be converted to PDF.

To add another email to the PDF file you just created, follow the same process, except select the pdf file you just created as the target.  The previous PDF file will be appended with your new email message.

EML Viewer Pro and Lite are very flexible email views. In addition to .eml files that are created by Outlook Express, Windows Mail and other email clients, they can also view and search Outlook .pst, .ost, and .msg files, and also .mht files. The PDF Append function works with all of the email formats supported by EML Viewer Pro and Lite.
